True. The plants need water and water is scarce. This is why they are spaced fairly.

The correct answer is - True.

Desert plants are widely spaced because of the lack of water in the deserts. They are highly adapted to manage to get every drop of water, be it through their roots or through their leafs or thorns. They have very big root systems, that are both very deep and very big in diameter, so it is practically impossible for them to be next to each other because their root systems are so big and also the lack of water and nutrients, if they are next to each other they will not be able to survive because while competing with each other none of the plants will be able to satisfy its needs.

According to the rank-size rule, which of the following is typically true of higher-order services, such as hospitals with a lar

lesya692 [45]

Answer: They have larger ranges and thresholds.

Explanation: The rank-size rule defines range as the longest distance that a customer will travel to purchase a good or service. Threshold is the minimum market needed to support the supply of a product or service. It is assumed that customers which travel longer distances to purchase a higher-order good or service, and a provider of such goods and services will require a larger customer base to make a profit. Thus, higher-order services have larger ranges and thresholds.

Geneva says that the only thing that is needed for people to hear the sounds around us is a vibrating object. Do you agree with

elena-14-01-66 [18.8K]

Answer:

A vibrating object produces sound waves. Energy needs to be transferred from the vibrating object to the ear through a medium..

Explanation:

Sound is transmitted through sound waves and waves transfer energy from the source of the sound to it environment in a pattern of disturbance and travels through a media. Sound waves carry energy parallel to the motion of the wave .

Since sound involve sound wave and energy as seen in the above explanation. We can not agree with Geneva given that in order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium as a result of radio frequency signals that are leaking into our air causing them to bounce,reflect, enabling them to be heard in the human hearing range.

Find an equation for the perpendicular bisector of the line segment whose endpoints

zzz [600]

Answer:

y= -7/2x-26/2 or y= -7/2x-13

Explanation:

To solve this question you need all of these formulas:

gradient: $\frac{y2-y1}{x2-x1}$ , Point-Slope $y-y1=m(x-x1)$ ,

perpendicular m $(m1)x(m2)=-1$ , Midpoint $(\frac{x1+x2}{2}$ , $\frac{y1+y2}{2} )$

and equation of a line $y=mx+c$

where m stands for gradient

First things first.

To start you have to know the data of the line that includes the two endpoints, so you calculate its gradient (m) of this line with the gradient fromula: $m=\frac{-4-(-8)}{5-(-9)}$ , which equals 4/14 or 2/7

(It can also be called rise/run) (Remember the rule of signs where - and - equal +)

with that information you can proceed with the point-slope or point-gradient formula, so you plug the values: y-(-8) = 2/7 (x-(-9)), which results in y+8=2/7(x+9) and then y+8=2/7x+18/7.

To finish the equation you move eight to the other side. To simplify things you can change it into a fraction as I did, and remember to change signs.

y=2/7x+18/7 -8 -> y=2/7x+18/7-56/7 . This gives us the number of y=2/7x-38/7, which is the equation of the first line.

Now to know the gradient of the second line you apply the formula of perpendicular bisector where m1 x m2 = -1. We know m1 (gradient of the first line) is 2/7, so m2 = $\frac{-1}{2/7}$ = -7/2. m2 is therefore -7/2

Now you have to know the midpoint between the two endpoints, which will act as the start point of the perpendicular bisector

M (midpoint) = $(\frac{-9+5}{2} ,$ $\frac{8+(-4)}{2} )$ , which give us the coordinates of (-2, -6)

(remember, x coordinate is always first)

with this point we can apply again the point-slope formula to know the equation of the line:

y-(-6)=-7/2(x-(-2)) -> y+6=-7/2(x+2) -> y+6=-7/2x - 14/2

Move the 6 to isolate the y

y=-7/2x -14/2 - 12/2

which equals y= -7/2x -26/2

To make sure the answer is correct.

A marine climate is generally characterized by

kicyunya [14]

Answer:

a. Milder weather in the summer but colder weather in the winter

Explanation:

The oceanic climate of the marine climate s dominated by fewer temperature extremes. Having a monthly mean temperature below 22 degrees. As precipitation is evenly distributed through the seasons.

In the polewards type of climate dominant precipitation in the form of snowfall is more frequent they have a mild west coast around the middle latitudes. All depending on the type of land and ocean surface.

Mostly the presence of milder climates around the world and is prevalent in most parts of Oceania.
